On the way to Emerald City, in the famous "Poppy Field" scene (in which Dorothy fell asleep) the "snow" used in those camera shots was made from 100% industrial grade chrysotile asbestos - despite the fact that the health hazards of asbestos had been known for several years. The gray circle and zig-zag pattern interrupting the yellow brick road outside the main entrance of Emerald City spell out OZ. The horses in Emerald City palace were colored with Jell-O crystals. The relevant scenes had to be shot quickly, before the horses started to lick it off.
*****The cache you seek is micro. As you enter the area, you will see the "green" of Emerald City before you. There you will find the cache. Please bring your own pen as this is very small.
